Generalized MPLS (GMPLS) Data Channel Switching Capable (DCSC)
and Channel Set Label Extensions
Abstract
This document describes two technology-independent extensions to
Generalized Multi-Protocol Label Switching (GMPLS). The first
extension defines the new switching type Data Channel Switching
Capable. Data Channel Switching Capable interfaces are able to
support switching of the whole digital channel presented on single
channel interfaces. The second extension defines a new type of
generalized label and updates related objects. The new label is
called the Generalized Channel_Set Label and allows more than one
data plane label to be controlled as part of a Label Switched Path
(LSP).

1. Introduction
This document describes two technology-independent extensions to
Generalized Multi-Protocol Label Switching (GMPLS). Both of these
extensions were initially defined in the context of Ethernet
services, see [RFC6004] and [RFC6005], but are generic in nature and
may be useful to any switching technology controlled via GMPLS.
The first extension defines a new switching type, which is called
Data Channel Switching Capable (DCSC). DCSC interfaces are able to
support switching of the whole digital channel presented on single
channel interfaces. The second extension defines a new type of

called the Generalized Channel_Set Label and allows more than one
